L'invention concerne un mécanisme oscillateur 100 isochrone d'horlogerie à oscillateurs couplés, qui est réalisé très simplement, par la combinaison de seulement deux oscillateurs primaires: ce mécanisme oscillateur 100 est constitué d'uniquement un premier oscillateur 10 et d'un deuxième oscillateur 20.The invention relates to an isochronous clock oscillator mechanism with coupled oscillators, which is realized very simply, by the combination of only two primary oscillators: this oscillator mechanism 100 consists of only a first oscillator 10 and a second oscillator 20.

Le premier oscillateur 10 comporte un premier moyen de rappel élastique 11, qui est fixé d'une part à une structure fixe 1 au niveau d'au moins un premier ancrage 12, et d'autre part à un premier mobile 13 pivotant autour d'un premier axe D1.The first oscillator 10 comprises a first elastic return means 11, which is fixed on the one hand to a fixed structure 1 at at least one first anchor 12, and on the other hand to a first mobile 13 pivoting around a first axis D1.

Le deuxième oscillateur 20 comporte un deuxième moyen de rappel élastique 21 fixé à un deuxième mobile 23.The second oscillator 20 comprises a second resilient return means 21 fixed to a second mobile 23.

Selon l'invention, le premier oscillateur 10 et le deuxième oscillateur 20 sont couplés l'un à l'autre, par liaison aérodynamique entre le premier mobile 13 et le deuxième mobile 23 ou/et par liaison mécanique par le deuxième moyen de rappel élastique 21 qui est alors fixé au premier mobile 13.According to the invention, the first oscillator 10 and the second oscillator 20 are coupled to each other by aerodynamic connection between the first mobile 13 and the second mobile 23 and / or by mechanical connection by the second elastic return means 21 which is then fixed to the first mobile 13.

De façon particulière, le premier moyen de rappel élastique 11 est unique, et le deuxième moyen de rappel élastique 21 est unique.In particular, the first elastic return means 11 is unique, and the second elastic return means 21 is unique.

Plus particulièrement, le premier oscillateur 10 et le deuxième oscillateur 20 sont couplés l'un à l'autre, à la fois par liaison aérodynamique entre le premier mobile 13 et le deuxième mobile 23, et par liaison mécanique par le deuxième moyen de rappel élastique 21 qui est fixé au premier mobile 13.More particularly, the first oscillator 10 and the second oscillator 20 are coupled to each other, both by aerodynamic connection between the first mobile 13 and the second mobile 23, and by mechanical connection by the second elastic return means 21 which is fixed to the first mobile 13.

Dans une réalisation particulière de l'invention, le deuxième moyen de rappel élastique 21 est un guidage flexible élastique à lames minces.In a particular embodiment of the invention, the second elastic return means 21 is an elastic flexible guide with thin blades.

Dans un mode de réalisation particulier et non limitatif de l'invention, le premier oscillateur 10 est de type balancier-spiral, et le premier moyen de rappel élastique 11 est un premier ressort spiral fixé à la structure fixe 1 par un premier piton constituant le premier ancrage 12. Et le deuxième oscillateur 20 est aussi de type balancier-spiral, et le deuxième moyen de rappel élastique 21 est un deuxième ressort spiral fixé au deuxième mobile 23.In a particular and non-limiting embodiment of the invention, the first oscillator 10 is of the spiral-balance type, and the first elastic return means 11 is a first spiral spring fixed to the fixed structure 1 by a first stud constituting the first anchor 12. And the second oscillator 20 is also of balance spring type, and the second elastic return means 21 is a second spiral spring fixed to the second mobile 23.

Dans d'autres modes de réalisation de l'invention, le premier moyen de rappel élastique 11, ou/et le deuxième moyen de rappel élastique 21 de couplage, est une lame élastique mince, ou similaire.In other embodiments of the invention, the first resilient biasing means 11, or / and the second resilient biasing means 21 is a thin elastic blade, or the like.

Dans une variante particulière de de mode de réalisation comportant des ressort spiraux, le deuxième spiral 21 est fixé, d'une part à la serge ou à un bras du premier mobile 13 en un deuxième piton 22, et d'autre part au deuxième mobile 23 qui pivote autour d'un deuxième axe D2. Et l'entretien du mécanisme oscillateur 100 se fait sur un seul des premier mobile 13 ou deuxième mobile 23.In a particular variant of embodiment comprising spiral springs, the second hairspring 21 is fixed, on the one hand to the serge or to an arm of the first mobile 13 in a second pin 22, and on the other hand to the second mobile 23 which pivots around a second axis D2. And the maintenance of the oscillator mechanism 100 is done on only one of the first mobile 13 or second mobile 23.

Dans une autre variante, l'entretien des oscillations est effectué indépendamment sur chacun des deux oscillateurs primaires 10 et 20.In another variant, oscillation maintenance is performed independently on each of the two primary oscillators 10 and 20.

Plus particulièrement, la raideur du deuxième moyen de rappel élastique 21 est inférieure à la moitié de la raideur du premier moyen de rappel élastique 11.More particularly, the stiffness of the second elastic return means 21 is less than half the stiffness of the first elastic return means 11.

Plus particulièrement encore, la raideur du deuxième moyen de rappel élastique 21 est comprise entre 0,30 et 0,40 fois la raideur du premier moyen de rappel élastique 11.More particularly still, the stiffness of the second elastic return means 21 is between 0.30 and 0.40 times the stiffness of the first elastic return means 11.

Plus particulièrement, l'inertie du deuxième mobile 23 est inférieure au tiers de l'inertie du premier mobile 13.More particularly, the inertia of the second mobile 23 is less than one third of the inertia of the first mobile 13.

Plus particulièrement encore, l'inertie du deuxième mobile 23 est comprise entre 0,20 et 0,30 fois l'inertie du premier mobile 13.More particularly, the inertia of the second mobile 23 is between 0.20 and 0.30 times the inertia of the first mobile 13.

Dans une réalisation particulière, le premier mobile 13 et le deuxième mobile 23 sont des balanciers.In a particular embodiment, the first mobile 13 and the second mobile 23 are pendulums.

Dans une autre réalisation particulière, le premier mobile 13 ou le deuxième mobile 23 est une cage d'un tourbillon ou d'un carrousel, et le deuxième mobile 23 ou respectivement le premier mobile 13 est un balancier.In another particular embodiment, the first mobile 13 or the second mobile 23 is a cage of a vortex or a carousel, and the second mobile 23 or respectively the first mobile 13 is a pendulum.

Plus particulièrement, le balancier constituant le deuxième mobile 23 ou respectivement le premier mobile 13 est coaxial à la cage du tourbillon ou carrousel constituant le premier mobile 13 ou respectivement le deuxième mobile 23, et est pivoté dans la cage. Le deuxième piton 22 du deuxième oscillateur 20 est fixé à un bras ou au tambour de la cage. Et l'entretien du mécanisme oscillateur 100 est effectué par une ancre 3 ou une détente coopérant avec un petit plateau fixé au tourbillon ou carrousel au niveau de son axe de pivotement.More particularly, the rocker constituting the second mobile 23 or respectively the first mobile 13 is coaxial with the cage of the vortex or carousel constituting the first mobile 13 or respectively the second mobile 23, and is rotated in the cage. The second stud 22 of the second oscillator 20 is attached to an arm or the drum of the cage. And the maintenance of the oscillator mechanism 100 is performed by an anchor 3 or a detent cooperating with a small plate attached to the vortex or carousel at its pivot axis.

Dans une réalisation particulière, et avantageuse pour permettre un couplage aérodynamique, la distance G minimale entre des parties de grand diamètre, notamment les parties de plus grands diamètres, du premier mobile 13 et du deuxième mobile 23 est inférieure à 0.5 mm. Ce couplage aérodynamique est favorable, même lorsqu'un couplage principal est effectué par le deuxième moyen de rappel élastique 21, car ce couplage aérodynamique tend à stabiliser le mécanisme oscillateur 100 sur un seul des deux modes (en phase ou en opposition de phase). Un couplage aérodynamique existe même avec des surfaces discontinues, par exemple entre des bras 4 d'une cage de tourbillon ou carrousel d'une part, et une serge 5 de balancier d'autre part.In a particular embodiment, and advantageous to allow aerodynamic coupling, the minimum distance G between large diameter parts, in particular the larger diameter parts, of the first mobile 13 and the second mobile 23 is less than 0.5 mm. This aerodynamic coupling is favorable, even when a main coupling is effected by the second elastic return means 21, because this aerodynamic coupling tends to stabilize the oscillator mechanism 100 on only one of the two modes (in phase or in phase opposition). Aerodynamic coupling exists even with discontinuous surfaces, for example between arms 4 of a vortex or carousel cage on the one hand, and a balance rod 5 on the other hand.

De façon avantageuse, le mécanisme oscillateur 100 comporte des moyens pour faire varier cette distance entre le premier mobile 13 et le deuxième mobile 23, de préférence dans la fourchette 0.1-0.5 mm.Advantageously, the oscillator mechanism 100 comprises means for varying this distance between the first mobile 13 and the second mobile 23, preferably in the range 0.1-0.5 mm.

La figure 5 est un schéma illustrant grossièrement l'allure que peut prendre la courbe de déphasage en fonction du temps, montrant qu'à une certaine valeur, notamment à proximité de 0.5 mm, le déphasage vient à se stabiliser à une valeur sensiblement constante. Bien sûr, une certaine durée ΔT de régime transitoire est nécessaire avant d'arriver à la stabilisation, par exemple de l'ordre de 200 secondes pour un oscillateur constitué de deux balanciers-spiraux d'horlogerie classiques, battant à 3 Hz, où les balanciers sont coplanaires et distants de 0.5 mm.The figure 5 is a diagram roughly illustrating the pace that can take the phase shift curve as a function of time, showing that at a certain value, especially near 0.5 mm, the phase shift comes to stabilize at a substantially constant value. Of course, a certain duration ΔT of transient regime is necessary before reaching stabilization, for example of the order of 200 seconds for an oscillator consisting of two classic clockwise spirals, beating at 3 Hz, where the pendulums are coplanar and distant of 0.5 mm.

Dans une réalisation particulière, le deuxième mobile 23 et le premier mobile 13 sont coaxiaux.In a particular embodiment, the second mobile 23 and the first mobile 13 are coaxial.

Dans une autre réalisation particulière le deuxième mobile 23 est, au moins en projection, à l'intérieur du premier mobile 13.In another particular embodiment the second mobile 23 is, at least in projection, inside the first mobile 13.

Dans une autre réalisation particulière, les parties de plus grands diamètres du premier mobile 13 et du deuxième mobile 23, qui sont positionnés sur deux étages différents, sont sensiblement de même diamètre et sensiblement en face l'une de l'autre.In another particular embodiment, the larger diameter portions of the first mobile 13 and the second mobile 23, which are positioned on two different stages, are substantially the same diameter and substantially opposite one another.

Dans cette dernière variante, et sans une réalisation particulière, le deuxième moyen de rappel élastique 21 est un deuxième spiral qui s'étend sur deux étages.In this latter variant, and without a particular embodiment, the second elastic return means 21 is a second spiral which extends over two floors.

Dans une autre réalisation particulière encore, le deuxième mobile 23 et le premier mobile 13 sont positionnés côte à côte et sensiblement coplanaires.In yet another particular embodiment, the second mobile 23 and the first mobile 13 are positioned side by side and substantially coplanar.

La figure 9 montre un couplage aérodynamique avec des rondelles ou billes, ou similaires, disposées entre deux balanciers. Cette solution, est aussi applicable à une variante de la solution de la figure 8, avec un troisième mobile positionné entre les deux balanciers. Plus particulièrement, au moins un troisième mobile est introduit entre les parties de plus grands diamètres du premier mobile 13 et du deuxième mobile 23, ce troisième mobile ayant uniquement la liberté de pivoter sur lui-même ou de glisser selon une direction orthogonale à la droite qui définit la distance minimale entre les parties de plus grands diamètres du premier mobile 13 et dudit deuxième mobile 23. Plus particulièrement encore, le troisième mobile est fixé à un troisième moyen de rappel élastique indépendant du premier moyen de rappel élastique et du deuxième moyen de rappel élastique pour définir un troisième oscillateur couplé par liaison aérodynamique aux premier oscillateur 10 et au deuxième oscillateur 20.The figure 9 shows an aerodynamic coupling with washers or balls, or the like, arranged between two rockers. This solution is also applicable to a variant of the solution of the figure 8 , with a third mobile positioned between the two pendulums. More particularly, at least a third mobile is introduced between the larger diameter portions of the first mobile 13 and the second mobile 23, the third mobile having only the freedom to pivot on itself or to slide in a direction orthogonal to the right which defines the minimum distance between the parts of larger diameters of the first mobile 13 and said second mobile 23. More particularly, the third mobile is fixed to a third elastic return means independent of the first elastic return means and the second means of elastic recall to define a third oscillator coupled by aerodynamic link to the first oscillator 10 and the second oscillator 20.

L'introduction d'un ou plusieurs mobiles permet d'assurer la stabilisation du système des deux oscillateurs couplés dans le mode en anti-phase, qui a une fréquence plus élevée. Chacun de ces mobiles pouvant être connecté à un moyen de rappel élastique indépendant, imposant une oscillation régulière de ce mobile. Dans le cas de balanciers, une telle variante est réalisable dans une exécution de type MEMS ou similaire, en matériau micro-usinable, de type silicium ou autre, ayant des guidages flexibles intégrés.The introduction of one or more mobiles makes it possible to stabilize the system of the two oscillators coupled in the anti-phase mode, which has a higher frequency. Each of these mobiles can be connected to an independent elastic return means, imposing a regular oscillation of this mobile. In the case of rockers, such a variant is feasible in a type of MEMS execution or similar, of micro-machinable material, silicon type or otherwise, having integrated flexible guides.

L'invention concerne encore un mouvement d'horlogerie 200 comportant au moins un tel mécanisme oscillateur 100.The invention also relates to a watch movement 200 comprising at least one such oscillator mechanism 100.

L'invention concerne encore une montre 1000 comportant un tel mouvement 200.The invention also relates to a watch 1000 comprising such a movement 200.
